Original Behaviour was using old methods for detecting entering/exiting universe, they are now all under the same hood and the original is kept for UniverseEntranceManager because it needs to enter the universe without itself. The internal behaviour kept under a subnamespace of "Core.Internal" for the purpose that it might come in handy for other use cases.
